Using this system, the radio can do the following:
Seek to stations broadcasting the selected type of
programming,
receive announcements concerning local and
national emergencies,
display messages from radio stations, and
seek to stations with traffic announcements.
This system relies upon receiving specic information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station

the time of day, a program type (PTY) for current

for two seconds. The radio will produce one beep
and selected display will now be the default.
